Networking research and development is an important field in information technology and its importance grows with the rise of the Internet and the ubiquity of worldwide communication. Besides theoretic analysis and simulation, testbeds are a key tool for research and development in this area. In the German-Lab project, a national Future Internet research project that combines both, research and experimentation, a flexible testbed has been developed. A part of the facility is the topology management tool (ToMaTo), a topology centric networking testbed. Currently ToMaTo has been deployed to over 120 nodes worldwide and has been successfully used in research as well as in education. ToMaTo has been designed to be an easy to use, flexible and resource efficient testbed for network research within virtual topologies. This presentation will show the concepts of G-Lab especially the Topology Management Tool and its applications in research and education. Moreover a short overview of a new project “Testbed on Demand” based on the NSF funded CloudLab infrastructure is given.


Paul Müller is professor for computer science at the University of Kaiserslautern. He received his PhD from the faculty of mathematics at the University of Ulm in the field of statistics. Thereafter, he was responsible for various research projects and the development of a statewide computer network in Germany. His current research interests are mainly focused on distributed systems, future internet-working architectures and service-oriented architectures. His research group Integrated Communications Systems Lab (ICSY) is aimed to a holistic view to communication systems avoiding local optimization in favor of an overall optimization.
